Interface Expression

All Superinterfaces:

Element, EModelElement, EObject, NamedElement, Notifier, OpaqueExpression, ParameterableElement, TemplateableElement, TypedElement, ValueSpecification

public interface Expression

extends OpaqueExpression

A representation of the model object 'Expression'. An expression represents a node in an expression tree, which may be non-terminal or terminal. It defines a symbol, and has a possibly empty sequence of operands which are value specifications.

The following features are supported:

• Symbol
• Operand

Method Detail

getSymbol

public java.lang.String getSymbol()

Returns the value of the 'Symbol' attribute. The default value is "".

If the meaning of the 'Symbol' attribute isn't clear, there really should be more of a description here...

The symbol associated with the node in the expression tree.

Returns:

the value of the 'Symbol' attribute.

See Also:

setSymbol(String), UML2Package.getExpression_Symbol()

setSymbol

public void setSymbol(java.lang.String value)

Sets the value of the 'Symbol' attribute.

Parameters:

value - the new value of the 'Symbol' attribute.

See Also:

getSymbol()

getOperands

public EList getOperands()

Returns the value of the 'Operand' containment reference list. The list contents are of type ValueSpecification.

If the meaning of the 'Operand' containment reference list isn't clear, there really should be more of a description here...

Specifies a sequence of operands. Subsets Element::ownedElement.

Returns:

the value of the 'Operand' containment reference list.

See Also:

UML2Package.getExpression_Operand()

getOperand

public ValueSpecification getOperand(java.lang.String name)

Retrieves the ValueSpecification with the specified 'Name' from the 'Operand' containment reference list.

Parameters:

name - The 'Name' of the ValueSpecification to retrieve.

Returns:

The ValueSpecification with the specified 'Name', or null.

See Also:

getOperands()

createOperand

public ValueSpecification createOperand(EClass eClass)

Creates a ValueSpecification and appends it to the 'Operand' containment reference list.

Parameters:

eClass - The Ecore class of the ValueSpecification to create.

Returns:

The new ValueSpecification.
